[提要]  對(duì)巨型鋼框架結(jié)構(gòu)的分析，采用連續(xù)化的數(shù)學(xué)模型和角變位移法建立了巨型柱、巨型梁的等效剛度方程式和二階內(nèi)力分析的角度位移公式，并舉例說(shuō)明其應(yīng)用，供方案設(shè)計(jì)時(shí)參考。
[關(guān)鍵詞]  巨型鋼框架結(jié)構(gòu)  二階分析

The second-order analysis of giant steel frame structure is discussed. The mathematical model of an equivalent continum is proposed and solved by the slope deflection method. Finally, a numerical example is shown for reference in designing.
Keywords: giant steel frame structure; second-order analysis
